Key Terminology

A number of terms used by SharePoint Portal Server differ from the terms used by the underlying Microsoft Web Storage System technology on which SharePoint Portal Server is based. You can usually ignore the Web Storage System terms and use the SharePoint Portal Server counterparts. However, when working with code that uses the automation libraries of SharePoint Portal Server that use the Web Storage System terminology—notably Publishing and Knowledge Management Collaboration Data Objects (PKMCDO)—it is important to keep track of which SharePoint Portal Server terms correspond to which underlying Web Storage System or PKMCDO term. In this document, the following terms are interchangeable.

In addition, it is important to note how the names of automation component ProgIDs differ depending on whether they are being called using early binding (common in compiled code) or late binding (the only option when using scripting languages). In early binding, most of the automation components of SharePoint Portal Server begin with the prefix PKMCDO, whereas when being called with late binding, they begin with CDO.
